Application filed March 10, 1902. Serial No. 97,592.

To (LZZ whom it may concern.-

therefrom such foreign substances as condensable hydrocarbons or solidcarbonaceous or other foreign substances by compression and friction andthe saturation of same with aqueous Vapor, preferably in the form of.

steam.

My lnvention embodies novel features, as

will be hereinafter set forth and definitely claimed.

In the manufacture of ordinary commercial gases certain substancesusually classed as impurities are removed with great difficulty andcannot be eliminated by the ordinary methods in general use of washingand scrub-' bing the gas, and I have found that if the gases containingsuch substances are compressed and subjected to considerable frictionalresistance, simultaneously bringing into contact therewith watery vapor,preferably in the form of steam, the substances described are condensedand saturated to such an extent as to greatly increase their specificgravity, thus causing the ready falling of same and permitting of theirrecovery and removal.

When steam is used for purposes of saturation, as described, it isfrequently necessary to remove same before using the gas, and this isbest accomplished by condensing it by passing same over cooled surfaces.

To accomplish the foregoing, I use the apparatus or modifications ofsame, shown in the accompanying drawings, of which the following is adescription.

Figure 1 represents avertical sectional elevation of the gas-condensingdevice embodying my invention. Fig. 2 represents a plan of same.

Similar numerals of reference indicate corresponding parts in bothfigures.

1 is a shell, preferably of cylindrical form and preferably composed ofmetal.

2 is an inlet-pipe to condenser 1.

3 is an outlet-pipe from condenser 1.

4 is an overflow-pipe from condenser 1, placed at such a height as topermit of the retention of a certain amount of water 6 in the bottom ofcondenser 1.

5 is an ordinary hydraulic seal which receives overflow-pipe at.

7 is a constriction in inlet-pipe 2 of much the same form andconstruction as an ordinary steam-jet exhauster.

8 is a steam-supply pipe fitted with a suitable controlling-valveextending into the inlet-pipe 2 and constriction 7.

9 is an open-work mass of suitable solid substance,as brickwork, overthe surface of which water is sprayed by admission through pipes 10.

The operation of this apparatus is as follows: Water is first admittedthrough pipes 10 and passing down over the surface of material 9collects in the bottom of condenser 1 to the height of the overflowconnection 4, in which condition the condenser is ready for thereception of gas, which is admitted through inlet-pipe 2, and by theexhausting action of the constriction 7, in combination with thosteam-pipe 8, is forced through the narrow constriction 7, which causesa considerable compression of the gases and the sii'nultaneoussaturation thereof with the steam entering through pipe 8, thus causinga condensing and collection of any foreign substance contained in thegas to such an extent as to greatly increase its weight,in which stateit will readily fall from the gas into the lower portion of thecondenser 1, containing the water 6, wherein it will be trapped andretained. The gas thus freed from the described foreign substances isstill saturated with steam and in a heated condition owing to same, inwhich state it passes upward through the cooled material 9, over whichwater issuing from pipes 10 is passing downward in a reversed directionto that traveled by the gas. The action is to condense the steam intocold water, thus thoroughly removing the same and permitting the gas toescape from outlet-pipe 3 in a thoroughly cooled and cleansed condition.

The condenser described above can be of any convenient form andconstruction, and I do not limit myself-t0 any particular design; but inordinary operation I prefer the arrangement as shown.

Having thus described my invention, I claim- An apparatus for cleansingmanufactured gases comprising a suitable casing to form a tion openinginto the lower portion of said chamber, a gas-inlet having a constrictedporwhile the lighter gas escapes contact therewith, and means forproviding a continual discharge of water into the upper portion of thechamber, substantially as described.

In witness whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
